Be it known that We, llf'DFiELn iii. iauiij Huns'r and ARTHUR O. Norris,citizens of the j United States, residing' at Swanipscotl, in the 1county of Essex and State of lilassaeliusctts, and lllakel'ield, .in thecount-iy of iddlesex and S tate of Massachusetts, respectively, hareinvented certain new and useful improvements in E.,elet-Stay-Joiningillaohines, of io which the following is a sj'iecilicalion.

Our invention relates to meer 'Lism fo;l joining` or splicingthe stajsused to reinforce the uppers of shoes along the eyelets thereof. Thesestars are made in two pieces and are 1 5 usually joined at theirabutting ends by hand, the joint being` made by using a splicing-pieceor by lapping the ends of the s on each other. The gluingl of these s;to "tl splicing-piece or to each et;

zo pressing have l'ieretofore bee' and the object of our "n" theoperationb'fm xans of a simple meeiianism which shall make the Workperformed more i certain and regular in the completed resul;`

2 5 and greater in quantity.:

T o this end our invention use of tape-feeding, moistening, mechanism,in combination with means pressing the conjoined si; -fps li i 3o theWhole being operated b y one siroke or a actuating-lever, and in certainarrangements of parts and eombinetioiis of elemenls set forthparticularly in the claims.

In the drawings herewith presented, Fig` r l is a side eleva ion of ourmech side Wall of the table being' bro Fig'. 2 is a 'ola-n view. Fe'.the line X X, Fig. 2. il a i, i View of a shoe-flap, show; the i'oi'm c.the

4o reinforcing-pieces A and B and the positior of the tape-strip O.

2 de the table, haring the upper j, ont s the sides 2', the rear l gs m,and die base-flanges im", the basellanges haring savoir-lioles l'orattachment to any suitable sand or support.

Attached the rear llauges by bolts and projecting remarcar-dlg' are thebrackets 3, on

un tric roll, moisening and feed rolls, rl the ieell-:zv-etuaiingmechanism are supported. These brackets might, ofcourse,

l rin tite form of a liquid-ccntainer 7, laying at its loner end anarranr lateral slot 7 of tire r-.idtii of tl e roller 6. Tio lon er endof tite contain-r is Mirrored, as sion n, and lilled nitii soulelifjuiii-absorbing material, :is felt r sponge 7" oiieh projects outsligltly tlrou( 'i the slot sulliciently to eone in contaet with tlieadhesive-faced surface of the tape from roll 5.

S and J are the feeding-rolls, \\'l;ich in the rotation dran' tile tapefrom its roll 5 and present it to tie cutter. Tie upper roll 8 is .looseand is mounted on a siaft S, carried in bearing-arms S, rigid with tilebracket. Tipo loner of ti ese arirs is broken away in Fig. 2, so as notto obstruct the vienv of tlze lor. er feed-roll sizalt.

Tie upper an( .loner Afeed-rolls preferably have circumferentialeorrugatiens on tlgeir faces to engage tipe tape, it being best tlrat aslittle roll-surfue should Contact n itisv tlc tape as possible,particularly on the adhesiveifaeed sido.

.lize lor-:er roll f) is mounted to turn with a shaft SY, niicii iscarried on tiie brackets 3. As ill be noted iu Fig, 2, tite sitaftprojects at one end beyond the line of the bracket,

IOO

` movements shall be even and regular.

and in order to accommodate this the material of the brackets is cut toand bent out- Ward to form an arm 3, in ivliicn the shaft is borne.Attached to the teecl-roll 9 to turn with it is a ratchet t :eel 10.

11 is a sleeve having rotative engagement with shaft 9 and locatedbetween the ratchet Wheel 10 and the end of arm 3". Projecting from thesleeve 11 are the arms 12 13. 13, as shown plainly in Fig. 8, carriespivoted to it a paivl 13, whose tooth engages ii itii the ratchet-Wheel10. T he paal is held depressed against the teeth by a spring, as by thecoiled spring 13.

The arm 12 projects outward and dovtnward from the sleeve 11 and isbifurcated at its lower end to form guides 12, in which the head 14 iscapable of adjustment. The head is screw-threaded parallel to the guides12, and through this passes the tineaded rod 14. At the outer ends theguides 12 are joined by a cross-bar 12". The threaded rod 1&1 projectsout through the bar 12 and is squared for the application of a vrench.

Pivoted to the side of the head 14 is a connecting-rod 15, which at itsother end llas pivotal connections u ith a treadle 16, pivoted at itsrear end in a suitable support 16.

In order to hold the treadle in its raised pcsition, We employ a spring17. it is to be understood in this connection that the base or table 2is intended to be supported on any suitable frame or standard (notsho'vn) at a convenient distance above tie 'lloor and that the upper endof the spring 17 is intended to be attached to said frame or support byan eye 17 or other attachment. Iiisrbeing an arrangement common to alarge variety of foot-operated mechanisms, v. e have not deemed itnecessary to snow it.

In order that the treadle may not be raised too iiigh by the force ofthe spring, ive provide it r itn an angularly-projecting stop 16, (shownin dotted line, rig. 1,) ti-:lich engages with a stud 16.

18 is a vertically-movable presser-block which fits closely in asuitable slot in the top plate of the table 2. Preferably the top plateand the presser-block should be ti ick enough to guide and hold thepresser-block irmly in any of its positions, so that its The upper faceof the presser-block has at its rear edge a longitudinal groove Whoserear margin forms a cutting edge 18.

Supported above the table 2 hy a base 19 is the finger 19, 'whichprojects immediately over the presser-cad 1S. The iinger 19 and base 19may be attached to the table 2 in any convenient manner, as by bolts orscrews, but at its middle, opposite tle rolls 8 and 9, it is raisedsuiciently above tie surface the table to leave a space or slot 19 fortile passage of the tape 5.

at end ci sienes The csped to give the rapid and sharp t-.riist to t..epresser-read necessary to cut oi the tape projecting through slot 19 andtigen en tige head L.ed t'e up- 'vvard extent oi its inovei 1t is, vir.en

the cam has turned so far t: `t tie roller 20 is at the outer extremityci cani-face21-the further movement of the cam acts, by its face 21, togive a final firm pressure to the conjoined ports ci theieiniorce-j-,iieees and the ta e .nst tile projecting linger or plate19. Acting agai lst t.; e raising rorce or t.:;e

cam is spring 20, attached above and to the presser-block and at itseti: er end to any suitable ived point, as the shaft 21. There may betrio of these springs.

rl"he cain-operati' g mechanism comprises an arm 22, projecting from asleeve 22,ifast on shaft 9, Whose outer end engages beneath the end ofan arm 2d, (shown in dotted lines in Figs. 2 and 3,) on the cani-shaft21. As the sha-int Q is turned it raises arm 22, Which pushes oir-*wardand upward on arm 241, rotating shaft 21 and its attached cam 21. it isnecessary that the shaft 9 shall be capable ci b ng turned tlnoughvarying degrees of a circle in rder to edniit ci the adjustment theiced, but the presser-block should have one length oi' stroke. To thated our mechi .isn'i so as to allciv the arm 22 to slip by the arm 24after the latter has been raised to its upright position. iiniediatel rthis has occurred a spring 25 acts to reverse the shaft and reverse themotion of the cam. r'liis spring 25 is connected at one end to the arm24 and at the other to the base the table 2. After spring 25 lies actedthe arm 22 must return past the a 24. To accomplish this, v; eiorii arni22 iviui movable end 23, capable cic be held rigid with the 22 di 1ingmove nt in one direction and ci giving when the arm is moving in theother direction. This is accoiirilislied by pivot .3 the end piece 23 tothe arm 22 yd providing it vvitli a rigid angular prcjec At the junctionci this aiiguiar pr l orio-n with the end piece is formed shoulder Whichengages With a stop 22" on the arm 22. A spring 23 pulls upward on theprojection 23.

On the under side of the sliding block 18 is pass.

In oidei' to limit the motion of the emu 21, We provide the shaft 21with :i projecting illu.- gei' 26, which when tlie ezuu lies ree :liedits loweuest position comes :i utep 26, projecting inwardly ii'oiu theside of ille iaible 2.
